Criteria for the WaterWare discrete multi-criteria optimization

The set of criteria to be analyzed can, in principle, be defined by the user interactively: criteria can be deleted from the set, and new ones can be defined in the KnowledgeBase with the KB Editor and added with the RECONFIGURE button. These will be set to a value of undefined for all existing alternatives, which the user then can edit.

However, the default procedure is to use alternatives generated by WRM and the criteria generated there.. A WRM scenario (normal model run or optimization scneario) generates the following default summary criteria (they can be exported for use with DMC with the button labeled: export criteria). Of course, any sectoral or even node specific riteria (the latter, however, only in sets for one and the same network !) can be added manually as well.
Please note: To make comparison between different structural alternatives and even different river basins possible, all criteria must be normalized to eliminate dominant effects of basin size or other basin characteristics.
